Ping Library fails in main branch, works in 3.0.2 and 2.7.4 #8555

[dduehren]

Library depends on the internal behaviour of esp_yeild(), which previously just suspended our USER task without doing anything else

ESP8266Ping/src/ESP8266Ping.impl.h

Line 51 in 934e701

esp_yield();

However, since 3.1.0 it will also call esp_schedule(), so the logic it implements that waits on it's own esp_schedule() no longer works
